The ratio of a circle's circumference to its diameter is a constant but irrational (meaning its precise value cannot be fully written out using traditional numbers) number called Pi (π).
Pi ~= 3.1415927
Circumference = Pi (3.1415927...) * Diameter (120 inches)
~= 376.991118 inches
~= 377 inches

How do you divide a circle with 9cm diameter in three equal parts?
Construct a circle with a 4.5 radius. The circle's circumference is 360 degrees. So mark out 3 by 120 degrees on the circumference and join them to the centre of the circle which will divide the circle into three equal parts.
What is the circumference when the diameter is 38.2?
Circumference = pi ( 3.1416, a constant) * diameter = 3.1416 * 38.2 = 120 sq. units
If a 120 degree arc is 12mm long what is the circumference of the whole circle?
360 degrees in a circle 120 degrees = 12mm 360 degrees = 36mm Therefore the circumference of the circle is 36mm.
What is the circumference of a circle with a length of an arc 28.61 with a central of 120 what is the circumference?
A central angle of 120 is one third of the circle, so the arc length of 28.61 is one third of the circumference. 28.61 X 3 = 85.83
How large will a circle be using 60 inch line or length?
Circumference will be 120 pi inches, ie 31 feet and very nearly 5 inches
